Thanks for the explanations guys. I am curious about your choices personally as well, if anyone wants to share. It's something I could never see myself doing, but I am intrigued by it, and who knows. I never thought I would become a liberal either, and that snuck up on me before I knew it.
As for the meat substitutes... some of them are GOOD! I have found a few veggie burgers (like a mushroom one from Morning Star Farms, I think) that is delicious. I have had some veggie "chicken" nuggets and meatless ribs that are yummy, too. I will buy that stuff even though I am pretty far from a vegetarian just because I like it, and I feel no need to substitute meat in my diet.
